APPARATUS FOR SPINNING TEXTILE FIBERS.

SPECIFICATION forming part Of Letters Patent NO. 603,068, dated April26, 1898.

Application filed November 10, 1896. Serial No. 611,649. (No model.)Patented in England November 7, 1895, No. 21,056.

To all whom it may concern:

Be it known that we, RICHARD TODD, man ufacturer, of Heather Bank,Heaton Chapel, and Jessa AINswoRTH SroTT, architect and 5 engineer, of 5Cross street, Manchester, in the county of Lancaster, England, subjectsof the Queen of Great Britain and Ireland, have invented certainnew anduseful Improvements in Apparatus for Spinning Texi tile Fibers, (forwhich we have obtained a patent in Great Britain, No. 21,056, datedNovember 7, 1895,) of which the following is a specification.

Our invention relates to improved means I for spinning yarns upon thebare spindle of the ordinary diameter in frames principally of thethrostle type. Under our invention the spinning is effected by the aidof an elastic whip-traveler and by mechanism the prin- 2o ciple of whichis set forth in certain prior United States patents, Nos. 40,957,40,958, 40,959, and 40,960, granted to Ernst Gessner and now in forceand also ina patent in Great Britain, No. 20,487 of 1894, granted to one2 5 of the present applicants, Richard Todd. In'

the specifications of the said patents a ferrule or ring fits thespindle loosely and carries a fixed rigid or elastic arm orwhip-traveler having an eye at the upper end through which 0 the yarnpasses to the cop or spindle. In the said foregoing specifications, andespecially in the said British specification of Todd, the said arm orwhip-traveler is a fixture on the ferrule or ring, and this is thesource of many 3 5 disadvantages both in the course of manufacture anduse. For example, the arm is apt to break at the bend, and if suchshould happen or should the arm or whip-traveler become otherwise unfitfor use the whole fer- 40 rule or ring requires to be removed from thering or race in which it is retained by bent fingers and either repairedor thrown away, both time and material being thus sacrificed. Under ourpresent invention we remedy these defects by making the arm orwhip-traveler separate from the ferrule or ring and forming both so thatthe arm can be readily attached or detached at pleasure and withoutremoving the ferrule from the race. The most convenient method is toform any suitable spring snap-joint, the socket to receive the butt ofthe whip-traveler being formed either directly on the ferrule or ring oron an arm or projection therefrom. YVhen the socket is formed in aprojection from the ferrule, the arm or whip-traveler may be madeperfectly straight from butt to tip or eye, which is a great conveniencefor cheap manufacture. \Ve might bend or form the foot of the arm so asto form a spring-butt snapping into a recess in the socket or We mightform the socket with a spring-catch to engage with the butt of the arm.hen a spring snapjoint is used, a tongue prolongation or presser may beprovided to effect a more read y disengagement and separation of the armfrom the ferrule. A spring snap-joint, however, is not essential, as anyother convenient means, such as a jam-ring or other ready means, mightbe used to effect the purpose of our in- Vention, which is to render thearm or whiptraveler separate from and readily attachable to anddetachable from the ring or ferrule.

By means of our invention We efiiect great economy both in time andmaterial and remove a source of mischief and loss which militatedgreatly against the commercial success of this type of spinningappliance.

Our invention also relates to improved means for more readily and easilymounting the aforesaid ring or ferrule, which carries the whip-traveler,in working position. Under the construction set forth in the said priorBritish specification of Richard Todd the said ring or ferrule isprovided at the foot with bent fingers, two being the most suitablenumber, which fingers run in a race formed in a socket-ring with cap,the said socket-ring being carried in a lifting rail or part beneath thecop. As it is extremely desirable, if not 0 indeed essential, to havethe confining race as small in diameter as possible, so as to diminishthe frictional resistance or drag upon the said fingers, it was underthe said prior arrangement necessary to introduce the fin- 5 gers firstinto the socket-ring and bend them out afterward or otherwise during theprocess of introduction. This was an operation which took considerabletime and care and interfered materially with the economical use of theinvention. Under our present invention the fingers can be properly bentand shaped before being placed in the race of the socket or carryingring. To effect this, we so form the ferrule that it becomes possibleand easy to slip the bent fingers of the ferrule into working positionin the race. Under the method which is most likely to be adopted we cutout or shape the sides of the ferrule opposite to the fingers so thatthe sides of the ferrule offer no obstruction to the insertion of thebent fingers. One result of so cutting out the ferrule is that itbecomes thereby greatly lightened. To facilitate the application of thecap or cover of the socket or carrying ring, we make it of such a sizethat it can be passed down through the curbing-sleeve, which surroundsand confines the whip-traveler. As this materially restricts thediameter of the said cap, we use a secondary cover-plate to cover in thesocket or carrying ring, and this cover-plate may be made in two or moreparts. The cover-plate is cut out in the center to receive the cap. Thusthe cap may be made small enough to pass through the curbing-sleevewithout reducing the size of the carrying or socket ring.

In order that our said invention may be fully understood, we will nowproceed to describe the same more particularly, reference being had tothe annexed three sheets of illustrative drawings.

On Sheet 1, Figure 1 is a general View of a spindle carrying a wound-oncop of yarn and furnished with a flexible whip-traveler of the indicateddescription. On Sheet 2, Figs. 2 to 16 illustrate various modes ofrendering the elastic or whip traveler readily attachable to anddetachable from the arm of the ferrule or part mounted loosely on thespindle. On Sheet 3, Figs. 17 to 20 show an improved mode of cutting outor shaping the ferrule or loose part mounted on the spindle, so that itcan be inserted into position in the ring-socket after the fingers atthe foot of the ferrule have been bent to the proper shape. Figs. 21 and22 show a mode of making the arms of the ferrule readily attachable anddetachable. Figs. 23 and 21 show our improved modes of introducing thecap or cover of the socketring through'the curbing-sleeve and ofretaining the socket and cap in position.

Referring to Sheet 1 of the drawings, Fig. 1 has been inserted chieflyfor the purpose of making the general arrangement and construction ofthe spindle and flexible whiptraveler more clear to the reader. Thespindle A is supported in the bolster-rail in the ordinary manner and isdriven from the whirl A. In this figure a cop Bis shown wound on thespindle. The flexible arm or whip-traveler O is carried on an arm D ofthe ferrule D, which is loosely mounted on the spindle. A balancing-armD exists on the other side of the ferrule. The ferrule D has projectingfingers D which run in a space between the two halves of a socket-ring EE, the said socket-ring being held in a lifting-rail F, which rises andfalls, so as to correspondingly centrif u gal force.

raise and lower the eye O of the whip-traveler O. The space behind theledges constituting the rail to receive the fingers D forms anoilchamber to contain lubricant. Above the rail F and carried in anotherrail F is a curbingring G, which surrounds the cop and prevents thewhip-traveler C from flying outward by When the apparatus is at work andthe building of the cop B is in progress, the whip-traveler O is rotatedby the draw of the yarn in the same direction as the revolution of thespindle, and the yarn is spun and drawn through the eye 0 just as in thecase of a ring-traveler; but suppose the yarn to be winding on the barespindle or cop-sleeve or on any part of the cop where from thedirectness of the pull or from other causes a strain greater than usualis thrown upon the yarn, then instead of pulling upon an unyieldingobject like the ordinary traveler (which only runs with greater frictionand hangs farther back the more directly radially the yarn pulls uponit) underour improvement the yarn pulling on the elastic arm O draws theeye 0 close up to the spindle or cop andcantin g the ferrule D on thespindle binds it thereon or causes it to have more frictional contacttherewith, so as to accelerate its speed, so that the whiptraveleroffers less resistance and breakage of the yarn is prevented. Thisgeneral sketch of'the operation of the flexible whip-traveler and partswill assist the reader to follow more intelligently the improvementswhich consti tute our present invention.

The general principle as disclosed in Gessners and Todds specificationshas never been followed up or made practically and commerciallysuccessful because of the insufficiency and impractical nature of thedetails. For example, it has hitherto never been proposed to dootherwise than make the flexible arm 0 in one piece with the ferrule D.Such a method of construction is subject to the disadvantage that theferrule and arm are difficult to make in one piece and are easilybroken. The result of such a breakage is that not only the arm but theferrule also is rendered useless and the ferrule requires to be removedand renewed.

According to our invention we make the flexible arm C easily attachableand detachable from the ferrule, so that if the flexible arm should bedisabled or broken it can easily be replaced without disturbing theferrule. This detachability of the flexible arm or whiptravelcr G fromthe ferrule is the essence of this portion of our invention. It will beevident that various means for quickly attaching and detaching the armor whip-traveler might be used. WVe do not confine ourselves to anyparticular method; but in order to give illustrations of several ways inwhich it can be done we have appended in Sheet 2 illustrations ofseveral methods which we have tested and found efficient.

In the drawings each figure, as a rule, covers and includes a sectionalview and a plan.

For example, as in Fig. 2, we form the arm D of the ferrule D with anoblong socket D or aperture, and we form the tail of the flexible arm 0with a spring-elbow, which snaps into the oblong socket, the curved endof the elbow entering ahole in the side of the socket. By pinchingtogether the projecting portion of the elbow at the foot the arm 0 canbe disengaged and drawn out. Fig. 3 shows a similar arrangement, thefree end of the springelbow on the arm 0 having a stamped-out projectionG which enters a similarly-shaped aperture or recess in the side of thesocket D The free end of the elbow projects above the socket D and bypinching this 'toward the arm C the latter can be disengaged. Fig. 4. isidentical with Fig. 3, except that the pressed-out lockin g or snapprojection O is on the same side of the elbow as the flexible arm 0. InFig. 5 there is no spring-elbow. The'arm C has a projection O, whichenters a recess in the socket .D", the arm being kept in position by atapered cotter I-I, driven down so as to wedge the tail of the arm C inposition. In Fig. 6 there is a spring-tongneD stamped out of thematerial of the socket I), and having a ridge at the back which engageswith a bend or crook 0 011 the tail of the arm 0. By pushing down thetailof the arm 0 into the socket D it snaps behind the spring D and bylifting the spring D the tail can be released again. In Fig. 7 thesocket has beneath it a pressed-out tooth or stop D which enters theloop of the elbow at the foot of the arm C. The free end of the elbowhas an inclined termination 0 which acts as a wedging-spring to draw upand hold the elbow against the tooth or stop I). In Fig. 8 the socket Ditself is formed as a spring-eye to nip and hold the flexible arm 0. Thefoot of the arm G is formed with an eye engaging with a tooth or stop D.In Fig. 9 the same formation of spring-socket is used, the foot of thearm 0 having a portion bent at right angles, which snaps into a hole inthe arm beneath the socket. In Fig. 10 the foot of the arm O has apressed projection or knee 0, which snaps into a recess made to receiveit in the spring-socket D. In Fig. 11 the crooked foot 0 of the arm 0 isheld in position by a cover D which is slid over the arm D after thepart G has been placed in position. The arm D might either be flatacross, as shown in the lower plan view, or it might be recessed toreceive the foot of the flexible arm 0, as shown at D in the planFig-11. In Fig. 12 the flexible arm C is held to the end D of theferrule-arm D by a sliding janrring D". In Fig. 13 the cover Di ishinged to the arm D, so as to turn over the traveler-arm O and secureit. In Fig. la the foot of the flexible arm 0 is made with a spring loopor eye, which engages with the suitably-shaped part D of the arm D. In

Fig. 15 the spiral or corkscrew formed foot of the flexible arm 0 isdropped into the socket D and held by a projecting finger engaging in anotch, while in Fig. 16 the similarly spiral shaped foot of the arm 0fits upon the cylindrical projection D from the arm D and is held by afinger projecting inward and engaging in a notch. In all of thesedifferent forms the flexible arm 0 is readily attachable to anddetachable from the arm D, so that if the flexible arm 0 should at anytime be disabled or broken it can easily and speedily be removed andreplaced by a fresh arm without disturbing the ferrule. Although we haveshown so many forms of this improved detachable connection between theferrule-arm and the whip-traveler, we do not, of course, confineourselves to these, and consider any ready means of attaching anddetaching the whiptraveler as within the scope of our invention.

Our invention also relates to improved means for enabling the ferrule Dto be more easily applied when the fingers D have been bent to theproper angle and shape. When using a socket-ring, such as E E, (shown inFig. 1,) it is essential to limit the confining race as much in diameteras possible, so as to diminish the frictional resistance or drag uponthe said fingers. In former casesfor example, in the aforesaid formerspecification of Richard Todd, No. 20,487 of ISSl-it was necessary tointroduce the fingers first into the race and then to bend them outwardat right angles to the ferrule. This was an operation which tookconsiderable time and care and interfered materially with the economicaluse of the invention. Under our present invention the fingers can beproperly bent and shaped before being placed in the race of thesocket-rin To effect this, we so cut out or form the ferrule that itbecomes possible and easy to slip the bent fingers of the ferrule intoworking position in the race. This new mode of formingthe ferrule isshown in Figs. 17 to 20, Sheet 3. We cut out or shape the sides of theferrule D opposite to the fingers D When this is done, the fingers canbe inserted into the race, the cut-out sides of the ferrule allowing itto be canted in the manner shown at Fig. 19, thereby permitting of theintroduction of the fingers D into the race. The spindle A may then bepassed upward or downward through the ferrule and socket-ring. Not onlydoes this cutting out of the ferrule enable the bentfingers D to beintroduced into the socket-ring race, but it has also the advantage ofgreatly lightening ICC IIO

the ferrule and redncin g frictional drag. An-

other method of introducing the already-bent fingers D of the ferruleinto the race is to render the arms D D detachable from the ferrule D.This improvement is illustrated in Figs. 21 and 22. Fig. 21 is avertical section of the ferrule and separately-applied arms, and Fig. 22is an exterior view of the ferrule without the arms, but with the upperhalf or cap of the socket-ring shown surrounding the ferrule. Theferrule D is formed with its fingers D bent to the proper shape and set.The ferrule is also formed with side snap-springs (Z, pressed out of thematerial. piece with a ring D from which the arms spring. The ring D isformed with perforations to receive projections d from the springs cl.In applying the ferrule we place the lingers D on the race of the lowerhalf of the socket-ring, then place the upper half of the socket-ring inposition, slipping it over the ferrule, and then snap the ring D,carrying the arms, upon the upper spring portion of the ferrule.

Figs. 23 and 24 illustrate improved means for introducing and holdingdown the caps E of the socket-rings E. /Ve effect this by means of clipsJ, secured to the lifting-rail F by screws K. This enables us todispense with threading the cap and socket to sore them together, as inthe said prior specification of Todd, or the provision of screwed studsto connect the ring and cap.

It is advisable to provide that the cap E shall be capable of beingpassed down into position through the curbing-sleeve G. Therefore weseek to reduce its diameter as much as possible. In Fig. 23 a ledge E isformed in the interior of the socket-rim g E, this ledge receiving andsupporting the outer edge of the cap E. The clips J, extending over thecap and ring, hold the cap in position. As the dotted lines show, thecap is sufficiently small to pass through the curbing-sleeve G. In Fig.24 a separate annular cover plate or ring L is seated in a check orrecess in the socket-ring E, and the cap E is placed over this annularring L, the clips J holding both ring and cap in position. In thisinstance also, as the dotted lines show, the cap can be passed throughthe curbing-ring G.

In combination the spindle to carry thecop, the ferrule arranged about the spindle at a point below theposition of the cop, and the whip-traveler attachably and detachablysecured to the ferrule below the cop and extending up along the cop withits free end directed upwardly, the attachment between the traveler andthe ferrule being rigid while the said Whip is flexible and adapted tobend throughout its length.
